i'm on a HUGE downswing myself, and i've also seen quads A LOT more than i ever saw before. I made quad fives on the flop and got 30 dollars from the Quad Pyramid promotion at Carbon aswell, i also made quad sevens on the flop aswell as more quads indeed, i was even going to consider mailing support for quad sevens on the flop to see if they give anything for that

(normally only quad fives).
So to answer your question: YES i very much have seen insane variance since the update.
